Confused about state of DUN on Sprint...

I'm trying to help a friend set up a DUN connection between a VAIO TX650P and a Treo 650. Right now, I'm very close, it seems. I can discover the device and it shows that the Dial-Up Networking service is available, but when I try to continue, it says, "Connection Failed."

Then I see threads on here in which patches are being written for Sprint and Bluetooth?

No, the patches were being discussed prior to the latest firmware released by Sprint when they had not yet enables DUN. With the latest firmware, you do not need to use the patched BT manager and should be able to set it up out the box...

FYI, if you still cannot make it work, there are 3rd party apps like pdanet that make it easy for you...

I have a bluetooth enabled laptop and have NEVER been able to get it to work with my sprint 650 no matter how many times I try, yet other bluetooth products work well with the laptop. I gave up and put out the money and got the product by JuneFabrics that gaurav referred to above. It worked seamlessly. The only problem with the pdaNet is that it is incompatable with Ptunes and it will nag you disable the pdaNet. If you need music and connectivity simultaneously this will not work for you.

I have an unlimited data plan with Sprint and have had no problems. Shannon, the Treo 650 specific PDANet supports DUN over bluetooth as well as USB. I had the previous version for the 600 and there is no discount for the upgrade. I find that it works well and does not cause any problems.

I don't know if this will make you feel any better, but I have had to set this up twice (once on a windows machine, then again when I switched to mac). Both times it was a pain, but once I worked through the bugs it was worth the effort. Everyonce in a while I need to do a soft reset (if I leave it connected too long or some other random thing), but overall it is great. Very few problems.
